ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
CAUTION:
DO NOT use center hole cone-type clamping machines to
hold the wheel assembly during tire removal/installation or
balancing or damage to the wheel paint, cladding or chrome
may result. Use only rim-type or universal lug-type clamp-
ing machines to hold the wheel assembly during servicing.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown. Refer to
.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks, and other damage. If deformed, remove wheel and check wheel
runout.
a. Remove tire from steel wheel and mount on a tire balance machine.
b. Set two dial indicators as shown.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown.
f.
Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout. In case a positive
or negative value is not available, use the maximum value (neg-
ative or positive) for total runout. If the total runout value
exceeds the limit, replace the steel wheel.

BALANCING WHEELS (ADHESIVE WEIGHT TYPE)
Preparation Before Adjustment
Remove inner and outer balance weights from the road wheel using releasing agent. Remove double-faced
adhesive tape from the road wheel.
CAUTION:
• Be careful not to scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean all traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and
skip Step 2. below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2.
to calculate the correct size adhesive weight.
1. Set road wheel on balancer machine using the center hole as a guide. Start the balancer machine.
2. For balancer machines that only have a clip-on (rim flange) weight mode setting, follow this step to calcu-
late the correct size adhesive weight to use. When inner and outer imbalance values are shown on the
balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that
should be used. Select the outer balance weight with a value closest to the calculated value above and
install in to the designated outer position of, or at the designated angle in relation to the road wheel.
a. Indicated imbalance value
×
5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz)
×
5/3 (1.67) = 38.33 g (1.35 oz)
⇒
40 g (1.41 oz)
balance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4
⇒
35 g (1.23 oz)
37.5
⇒
40 g (1.41 oz)
3. Install balance weight in the position shown.
CAUTION:
• Do not install the inner balance weight before installing
the outer balance weight.
• Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
• When installing balance weight (1) to road wheel, set it into the
grooved area (A) on the inner wall of the road wheel as shown
so that the balance weight center (B) is aligned with the bal-
ancer machine indication position (angle) (C).
CAUTION:
• Always use genuine NISSAN adhesive balance weights.
• Balance weights are non-reusable; always replace with
new ones.
• Do not install more than three sheets of balance weight.

4. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top another.
5. Start balancer machine again.
6. Install balance weight on inner side of road wheel in the bal-
ancer machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
7. Start balancer machine. Make sure that inner and outer residual
imbalance values are 5 g (0.17 oz) each or below.
8. If either residual imbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
TIRE ROTATION
• Follow the maintenance schedule for tire rotation service intervals.
MA-11, "FOR USA AND CANADA : Introduction to Peri-
(United States and Canada), or
MEXICO : Periodic Maintenance Schedule"
(Mexico).
• When installing the wheel, tighten wheel nuts to the specified
torque.
CAUTION:
• Do not include the spare tire when rotating the tires.
• When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wheel nut at torque exceeding the
criteria for preventing strain of disc rotor.
• Use NISSAN genuine wheel nuts for aluminum wheels.
• Perform the ID registration, after tire rotation. Refer to
WT-6, "ID Registration Procedure"

REMOVAL
1. Remove road wheel and tire assembly using power tool.
2. Remove valve cap and valve core to deflate the tire.
NOTE:
If the tire is to be reused, apply a matching mark on the tire in line with the position of the road wheel valve
stem assembly for the purpose of road wheel and tire balance adjustment after installation.
3. Remove the valve stem nut and allow transmitter to fall into tire.
4. Lubricate the tire outside bead well with a suitable non-silicone lubricant, and remove outside of tire from
the road wheel. Reach inside the tire and remove the transmitter.
CAUTION:
• Do not use silicone lubricant. Use of silicone lubricant will deteriorate the tire and road wheel.
• Be sure not to damage the road wheel or transmitter.
• Do not allow lubricant to make contact with transmitter.
5. Lubricate the tire inside bead well with a suitable non-silicone lubricant, and remove inside of tire from the
road wheel.
